Podcast 543: What's up with WhatsApp

After a security-focused podcast last week, we turn to...more security stories, like the so-called backdoor in WhatsApp (http://www.macworld.com/article/3157458/security/whatsapp-vulnerability-could-expose-messages-to-prying-eyes-report-claims.html) and how to keep those communications safe (http://www.macworld.com/article/3157562/security/the-backdoor-that-never-was-and-how-to-improve-your-security-with-whatsapp.html). And then Meitu got a lot of flack on the Android side, but Glenn can explain why iOS users shouldn't be as concerned (http://www.macworld.com/article/3160024/security/meitus-photo-effects-app-tracks-users-without-disclosing-enough.html).
